I really don't think marquez would be willing to fight mayweather again cuz floyd would ask for testing again which would show marquez coming into the fight with a diffrent physic,memo worked with him on the third paqiou fight and marquez did not look like he did on this fight so memo did what he is best at,after all he wasent helping olympians win metals simply with his coaching skills,if u know what to look for it is pretty obvious and u could see it on juans face that's why his face looks diffrent,a friend of mine was taking some some strong hormone type pills for the gym and didn't even stack it with a growth hormone and in just two months he started getting pretty big and would laugh in disbelieve cuz he could work out for 3 hours straight working out really hard and with heavy weights but sure enough u could see it in his face more on jaw area and forhad above eyebrows so juans going to avoid a fight with random testing trust me Ive been around gyms long enough so its something that is very obvious to me.

yeah if floyd demands more extensive testing it would mean cancellation of the fyt.. they would both test positive...
